UNITED STATES PATENT OFFICE BUSH Charles Greif Raible, Shaker Heights, Ohio, assignor to The Fanner Manufacturing Company, Cleveland, Ohio, a corporation of Ohio Application May 7, 1934, Serial No. 724,342 Claims. (Cl. 27-99) This invention relates to a tap or faucet bush time producing a tight connection. The bush I4 used in conjunction with a beverage barrel or keg has a cylindrical hollow extension I6 formed inan improved bush which is simple in construcper end of the extension being provided with a 5 tion, eilcient, and inexpensive to manufacture. laterally extending flange I1. 5 A further object of the invention is to provide A .tap attaching device I 8 has a hollow body l0 troduced into the barrel or keg in lling the same other.

The upper surface of the extension IB is 'g. 21s a vertical cross-sectional view of a tap COHVeX, as ShOWn at 24, S0 as t0 PIOVl'de a tight or faucet bush embodying the invention and upon connection irrespective of the alignment of the an enlarged scale, cooperating members. 30 Fig. 3 is a top plan view taken along line 3 3 The upper .end of the body member I9 is exof Fig. 2; and

g. 4 is a vertical sectional view snowing the portion of the member 22 is likewise exteriorly valve means with the movable valve member in screw threaded at 26, the screw threads however open position, extending in opposite directions. A wing nut 21 35 In the drawing I0 indicates a barrel or keg of interiorly Screw threaded is adapted to cooperhaving the top or head I2 secured Within the outer dl'reCOn the member 22 iS mOVed dOWnWardly 40 be had, opposite direction the member 22 is moved up- The head I2 is provided with an opening I3 Wardly with the result that the washer 23 is re- 45 extending therethrough and of any desired diammoved from engagement with the extension I6.

eter, which receives the screw threaded end of The body portion I9 has a transverse S1012 DTO- a bush I4. 'I'he bush I4 is secured to the head vided in its wall through which extends one end with the Aouter surface of the head I2 and limits munication with the opening provided in the `5 the inward movement .of the bush, at the same ymember' 22. The exposed end of the nipple 28 55 has secured thereto one end of a flexible hose 29, the other end of the hose being adapted for conof pressure.

30 has an opening extending therethrough and is adapted to be disposed within the tap connecting device I8 as shown in Fig. l. The rod is inserted at the upper end of the member 22 and through the opening provided therein and lowered until the end of the rod is positioned at the proper location with respect to the bottom of the barrel. The outer end of the tap rod, whichu is not shown herein, is of course provided with the customary tap through which the beverage is discharged, the same being withdrawn from the interior of the barrel. To provide a secure and pressure tight connection between and the member 22 an exteriorly screw member 3| cooperates with interior screw threads provided in the outer end of the member 22 and is adapted to be rotated into engagement with a rubber washer mounted within the member 22. A lever 32 is formed integral with the member 3l to enable thermember 3l to be readily turned and by turning the member 3| in one rubber washer is caused to contract and grip the tap rod 30, while movement in the opposite direction causes the pressure on the rubber washer to be relieved so that the tap rod may be either withdrawn or inserted as desired. It is to be understood that the beverage within the barrel is readilyT withdrawn through the tap rod 30 due to the pressure created within the barrel through the medium of the pressure hose 29.

The Vforegoing description, while forming no part of the present invention is typical of one of a number of tapping systems kand is illustrated here for the purpose of more clearly disclosing applicants invention and therefore it should be understood that the invention is not to be limited to its use with any particular type of tapping system.

It is the accepted practice to supply barrels at the present time or kegs to the trade containing at least one bung or tap bush such as indicated at posed surfaces 'duced or withdrawn in normally jtect the same Y the latter Vis sprayed upon the interior of the I4. A cork or other stopping means is inserted in the opening of the cylindrical extension I6, which acts as a seal, but frequently after the bevhas been removed from the barrel this precaution of plugging the opening is overlooked or carelessly pursued, with the result that certain objectionable matter enters through the exposed opening and becomes deposited in the barrel. In many cases consequently oi flavor.

The interior of the barrel is subjected to a vspraying operation through Athe usual opening Yprovided in the side to provide an impervious coating 33, such as pitch. This coating, in many instances, is an eighth of an inch in thickness and the pitch is sprayed at aV temperature of approximately 400 F. and, of course, covers all exn withinkrthe barrel.

It isA the primary feature ofthe present invention to providea valve means for vmaintaining the opening Vthrough which the beverage is introclosed position,

the beverage introduced therein is said means being under tension enclosed Vor encased in such a manner as to profrom the heat of the pitch when barrel, as the high temperature of the pitch and the subsequent hardening of the same would have a disastrous effect upon the tension means and render the same either inoperative or at least inthis deposit cannot be removed andV effective. Additionally,

ich is normally face, as more clearly This member ing 36 in alignment with the opening provided. in the circular extension I6 of the The bottom of the opening 3B at 3'i to provide a valve seat, the surface of which should be preferably ground in order to produce a fluid-tight connection, this valve seat clearly shown in Fig. 4. A movable is complementary tapered and preferably ground so as to tightly movable' valve member an extension 4D which projects provided in the member 34 and is pivotally conthe member means of a pin 42 having its Vends secured within the member 34 as more clearly shown in g. 4. This extension 40 has an integral ear 43 which extends upwardly and is normally disposed within the groove 35. A spring 44 is disposed within the groove 35 and a portionthereof extends through an opening 45 provided in the ear 43. This spring is of sufficient strength to cause the movable valve member 38 to assume a normally closed position but will yieldably permit the valve member to be moved away from the valve seat by the use of a proper implement or yprojecting the tap rod 30 through the opening into engagement with the movable valve member, as more clearly shown in Fig. 1. A stop 46 may be provided upon the member 34 Within the groove 35, as shown in Fig. 3, for engagement by the adjacent ends of the spring 44 so as to prevent the wire from creeping out of alignment and accidental disengagement between the spring 44 and the movable valve member.

Y The member 34 is adapted for attachment with the bung bush I4 asV shown in Fig. 2, and it is preferable to provide a recessed portion disposed. provided in the member 34 and the bottom ofthe bung bush I4, the latter being screw threaded to receive the.

attaching screws 4 While it is desirable that the member 38 be made d detachable element with respect to the bung bush I4, it is, of course, understood that this construction may be tegral for the purposes intended, be understood that the vmeans are intended for insertion into the barrel as a unitary structure.

In employing the valveY means plicants invention, attached is inserted in the head of the barrel in the manner already explained, and subsequently ythe spraying apparatus is introduced with a valve seat through a slotted opening 4l s 2,040,499 3 through the opening provided in the side of the Jacent said body portion, a movable valve membarrel. ber mounted on said member and adapted to While I have described the preferred embodiclose said opening therein, and a. spring member ents of the invention, it is to be understood disposed in said groove and operatively connectto said movable valve member for maintaining the latter in normally closed position. ber and adapted to close the opening therein member for maintaining the latter in normally I
